The invention discloses an elevator alarming positioning system and method. A piezoelectric power generation module and a power conversion unit are arranged under an alarming key; and when the alarming key is pressed, mechanical energy can be converted into electric energy, and generated alternating current is converted into direct current meeting use requirements of an alarming signal transmission unit and the direct current is supplied to the alarming signal transmission unit, so that an alarm can be given when the power is off, and furthermore, the problem that the elevator alarming positioning system cannot work when the power is off or a battery is exhausted can be solved. By encoding each elevator, codes are transmitted when an alarming signal is transmitted, and accurate floor positioning can be carried out; and the problem that a broken elevator cannot be rapidly positioned is solved.
